Prague Integrated Transport ( Czech: Pražská integrovaná doprava, PID) is an integrated public transport system providing services in Prague and within the Central Bohemian Region. It is run by a city-owned transit authority called Regional Organiser of Prague Integrated Transport (ROPID). Prague Integrated Transport includes metro, tram ...
Process identifier. In computing, the process identifier (a.k.a. process ID or PID) is a number used by most operating system kernels —such as those of Unix, macOS and Windows —to uniquely identify an active process. This number may be used as a parameter in various function calls, allowing processes to be manipulated, such as adjusting the ...
Principal ideal domain. In mathematics, a principal ideal domain, or PID, is an integral domain (that is, a commutative ring without nonzero zero divisors) in which every ideal is principal (that is, is formed by the multiples of a single element). Some authors such as Bourbaki refer to PIDs as principal rings .
A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on ...
Fundamental operation A block diagram of a PID controller in a feedback loop. r(t) is the desired process variable (PV) or setpoint (SP), and y(t) is the measured PV.. The distinguishing feature of the PID controller is the ability to use the three control terms of proportional, integral and derivative influence on the controller output to apply accurate and optimal control.
Service 01 PID 78 and 79 - Exhaust Gas temperature (EGT) Bank 1 and Bank 2. A request for one of these two PIDs will return 9 bytes of data. PID 78 returns data relating to EGT sensors for bank 1, whilst PID 79 similarly returns data for bank 2. The first byte is a bit encoded field indicating which EGT sensors are supported for the respective ...
Pelvic inflammatory disease, also known as pelvic inflammatory disorder ( PID ), is an infection of the upper part of the female reproductive system, namely the uterus, fallopian tubes, and ovaries, and inside of the pelvis. [5] [2] Often, there may be no symptoms. [1] Signs and symptoms, when present, may include lower abdominal pain, vaginal ...
Program-specific information (PSI) is metadata about a program (channel) and part of an MPEG transport stream . The PSI data as defined by ISO/IEC 13818-1 (MPEG-2 Part 1: Systems) includes four tables: The MPEG-2 specification does not specify the format of the CAT and NIT. PSI is carried in the form of a table structure.
